This study investigated the differences in patient experience by arrangement type of medical tourism facilitators(MTF) from the pre-visit to visit stages. Specifically, patient experiences from each stage with different service providers (MTFs and medical institutions) were measured: provision of information and respect for patient preferences as pre-visit experiences with the facilitators, communication and concierge services as visit experiences with the facilitators, and medical services as medical institution experiences. The scale to measure foreign patients' experiences was modified from the 'Picker in-patient questionnaire(PPE)' and the 'Picker patient experience questionnaire(PPE-15)'. Quantitative data were collected by conducting a self-administered questionnaire on 173 patients from China, Russia, Mongolia, and Kazakhstan. Qualitative data were collected by conducting in-depth interviews with 9 patients and 9 service providers. The data were collected between January and October in 2019. Quantitative data was analyzed by SPSS 25 for Chi-squared test and ANOVA, and qualitative data were analyzed based on keywords. The main results are as follows. When foreign patients used only overseas MTFs, they had a relatively positive patient experience in respect of receiving pre-visit information(F=7.47, p<.01) and respect for patient preferences(F=3.11, p<.05). Looking at both domestic and overseas facilitators during the visit, the patient experience was relatively negative for communication(F=3.75, p<.05). Regarding medical institutions, patients had a relatively negative patient experience with regards to medical services when they used both domestic and overseas facilitators(F=6.49, p<.01). The implications of this study are as follows. Patients should have a seamless and high-quality experience regardless of the facilitator arrangement type. This can be prepared through service standardization for the service providers. It would be also necessary to consider each other's features and problems at the institutional level and to improve service coordination by having service providers periodically communicate with each other.

This research validates the correlation between usability and functional attributes whilst comparing the degree of satisfaction of information framework used in museum mobile apps via usability evaluation in pre-visit setting. In cases of Bilbao Guggenheim and American Natural History Museum apps, the degree of satisfaction measured for information service, functional attributes, motivation for actual museum visit and during-visit usability of the apps were all highly evaluated. Such evaluation data indicates the increased usability of apps when mobile applications take user-friendly design that intuitively reflect users' interests and needs. After thorough analysis of correlation between usability and fictional attributes, data pointed to more meaning relationships existed in non-intrusiveness and personalization than other functional attributes. In conclusion, we were able to acknowledge the usability of museum mobile apps depends upon the interaction between content and functional attributes rather than entertainment factor and technology.

This research sheds light on the non-intrusive traits of mobile devices (Electronic Guidebook, Rememberer, I-Guides and eXspot) deployed in Exploratorium for enhancing visitor experience via case studies. In an interactive exhibition environment, non-intrusiveness was the key to supporting the immersive experience and meaning-making for visitors. The usability of hand-held devices directly impacted on the non-intrusiveness, thereby reshaping the form-factors of mobile devices. The change in from-factor has also minimized the functions of devices as the remember of museum experience. Furthermore, the role of mobile devices, which turned from a supposed multi-media guide to a mere rememberer, made them virtually impossible for realizing the "seamless visiting model" originally planned. An array of projects carried out in Exploration have achieved some degree of success such as increasing viewing time as well as reinforcing post-visit activities. However, taken from musicological perspective, increase in viewing time is by all means insufficient to be taken as proof since it is assumed to be achieved by photo-taking (i.e. MyExploratorium) rather than by interacting between visitors and exhibits. This issue --increased viewing time -- needs to be analyzed in depth. All in all, mobile devices used in Exploratorium can be defined as a learning tool/educational supporting medium based on personalization for (visitors') optimizing extended museum experience.

Future wireless systems will be required to support the increasingly nomadic lifestyle of people. This support will be provided through the use of multiple overlaid networks which have very different characteristics. Moreover, these networks will be required to support the seamless delivery of today's popular desktop services, such as web browsing, interactive multimedia and video conferencing to the mobile devices. Thus one of the major challenges in the design of these mobile systems will be the provision of the quality of service (QoS) guarantees that the applications demand under this diverse networking infrastructure. We believe that it is necessary to use resource reservation and adaptation techniques to deliver these QoS guarantee to applications. However, reservation and pre-configuration in the entire service region is overly aggressive, and results in schemes that are extremely inefficient and unreliable. To overcome this, the mobility pattern of a user can be exploited. If the movement of a user is known, the reservation and configuration procedure can be limited to the regions of the network a user is likely to visit. Our proposed Proxy-UMP is not sensitive to increase of the search cost than other schemes and shows that the increasing rate of total cost is low as the SMR increases.

Providing a mobile host with its required QoS is highly influenced by its mobility. The resource ReSerVation Protocol(RSVP) establishes and maintains a reservation state to ensure a given QoS level along the path from the sender to the receiver. However, RSVP is designed for use in fixed networks and thus it is inadequate in the mobile networking environment where a host changes its point of attachment. In this paper, we propose a new resource reservation protocol, RSVP-RA(RSVP by RSVP Agent) for mobile hosts. Our protocol assumes IETF Mobile IP as a mobility support mechanism. The proposed protocol introduce a new protocol entity - RSVP agent - to manage reservations in a mobile host's current visiting network. RSVP Agent is located in a local network and makes resource reservations in neighboring cells that the mobile host is expected to visit in the future. Thus, the proposed Protocol can provide a seamless QoS to the mobile host and significantly improve the scalability problem of RSVP by reducing the end-to-end signalling messages acrossing the backbone networks. The proposed protocols reduce packet delay, bandwidth overhead and the number of RSVP messages to maintain reservation states. We compared the performance of our proposed protocol with other proposed protocols in terms of signalling overhead, packet delay by simulation.

Omni-channel enables businesses to provide a seamless customer experience by organically integrating data from multiple channels. Customers have increasingly used mobile applications to place orders and make payments in offline stores. In such context, this study investigated the effects of customer experiences on brand loyalty via offline and mobile channels. Additionally, it examined the role of habit in establishing brand loyalty in a daily service environment. This study confirmed the importance of functional, human, and mechanical cues on perceived value in the offline channel. Additionally, differences in the influence of customer experiences via offline and mobile channels on brand loyalty were examined at based on the age and gender. The research model was empirically validated using survey data collected from 365 customers who visit coffee chains via mobile applications. The analysis results found that both perceived value of offline stores and loyalty to mobile applications have a significant effect on brand loyalty. Habit plays another critical role in enhancing brand loyalty. The findings of this study help service providers better understanding of the formation mechanism of brand loyalty in the context of omni channel and will be able to develop more effective marketing and operations strategies.
